Boo Buddy Swarms[1] are Boos known for forming large groups to attack.


Super Mario World[edit]

In Super Mario World, they are found only in the Donut Ghost House and Forest Ghost House. They are usually transparent, which is when they are harmless, but periodically will turn opaque, which is when they are dangerous, to dive at Mario. They are indestructible and can only be avoided by the player.

Yoshi's Story[edit]

In Yoshi's Story, swarms of miniature Boos called Little Boos[2] or Baby Boos[3] appear in Ghost Castle. These tiny ghosts will swoop at Yoshi very rarely, unless he throws an egg at one of the members of the group. Then, all of the Boos will stop in their tracks and swoop at Yoshi. It is impossible to defeat all of the Boos, as more will just appear from off-screen. If Yoshi eats a Heart Fruit and does a Ground Pound near them, they will turn into Lucky Fruit, much like Shy Guys do. Unlike their Super Mario World counterparts, they don't turn transparent and can be destroyed.

Mario Kart series[edit]

Boo Buddy Swarms appear in the Ghost Valley courses in Super Mario Kart, Banshee Boardwalk in Mario Kart 64, and Luigi's Mansion in Mario Kart DS. However, the Boos don't hurt the players.

Paper Mario: Sticker Star[edit]
